Hello! I have a Mppt 100/30 Victron Solar Panel regulator, how do you plug it in to get the dump relay to provide 12V to a hot water heater when the batteries are fully charged? A schedule would be good, I'm not sure where to charge 12V.
Regards Roger
Do you have a BMV or other shunt?
Do you have a GX device?
You need a BMV, this can be configured to switch a suitable relay using the switching relay in the BMV.
OK thank's Kevgermany!
But if I connect a BMV and a relay, where do I get + the supply to the heating element. If I take it directly from the solar panels, the voltage is too high, and if I take the voltage after the controller, the controller senses that something needs power and goes into bulk or absorption mode and then also starts charging the battery again?
It's 12V battrybank.
